This paper describes the state of the art in wavelength conversion and supercontinuum generation using glass-clad silicon core optical fibers. Such semiconductor fibers have enjoyed considerable attention due to their intrinsically high third-order nonlinearities, which are markedly higher than in conventional infrared glasses. Results to date from small core silicon fibers fabricated using both the...
Transparent ceramics of Y2O3 doped with 0.5 mol% Tm were fabricated starting from the synthesis of the precursor nanopowder by co-precipitation and calcination followed by its consolidation into fully dense ceramics. Densification and optical transparency of the ceramic were achieved by means of sequential steps of cold isostatic pressing at 206 MPa, vacuum sintering using the two-step method at 1500...
